试过了sudo apt-get clean，没有任何反应。sudo apt-get upgrade表示没有什么需要升级的。sudo apt-get check也找不到任何东西。

在 Windows 10 上使用 Ubuntu。

Answer 1

您可能更改了文件/tmp夹的文件权限，请检查

ls -lad /tmp

的正常设置为/tmp1777，ls显示为drwxrwxrwt. 那就是：完全开放，除了只有文件的所有者才能删除它（这就是这个额外t位对目录的意义）。

如果设置错误，您可以使用以下方法恢复它们：

chmod 1777 /tmp

我建议在进行此更改后重新启动机器。

注意：也/var/tmp以同样的方式检查，也许你有同样的错误

对我来说，我使用的是 Docker 容器，并/tmp在容器中安装了一个目录，这导致了冲突。我删除了安装的目录/tmp并允许apt update工作。
